The African Elephant: Giant of the Savannah
The African elephant is the largest land animal on Earth, known for its long trunk, huge ears, and curved tusks. These gentle giants live in herds (群体) across the savannas and forests of Africa. Elephants are herbivores, spending up to 16 hours a day eating grass, leaves, and bark.
Sadly, African elephants face severe threats. Poaching for ivory is the biggest danger, with thousands killed each year for their tusks. Habitat loss due to agriculture and human settlements also forces them to compete with humans for resources. In some areas, elephants are hunted as pests when they raid crops.
Conservation efforts are underway to protect these magnificent creatures. Organizations like the African Wildlife Foundation are training rangers to stop poachers and creating corridors (走廊) for elephants to move safely between munity programs teach farmers how to coexist with elephants without conflict.
Scientists estimate there are around 415,000 African elephants left in the wild, down from millions just a century ago. Protecting them is not only about saving a species but also preserving the ecosystems they help maintain. Elephants play a crucial role in dispersing seeds and shaping the landscape, making them “ecosystem engineers.”
